Mechanism of vascular relaxation by cholinomimetic drugs with special reference to pilocarpine and arecoline

The muscarinic receptor-mediated and non-muscarinic vascular effects of cholinomimetic drugs used in glaucoma were quantified. On the isolated rat aorta, the vascular tone induced by phenylephrine is functionally antagonized by cholinomimetic drugs. Based on EC50, the relative order of potency for the endothelium-dependent vascular relaxation was acetylcholine (0.05 muM) 1 > (¡À)-methacholine (0.35 muM) 1/7 > carbachol (0.63 muM) 1/12 > (¡À)-aceclidine (1.26 muM) 1/25. The maximal effects of the four agonists varied between 82-87%. The muscarinic vascular relaxation of 0.03 muM to 100 muM pilocarpine was less than 15%. At high concentrations, pilocarpine had 1/20,000 the vascular activity of acetylcholine. Physostigmine failed to potentiate the vascular relaxation of exogenous acetylcholine, indicating the absence of acetylcholine esterase in the tissue. Arecoline, with an EC50 of 7.76 muM, was partly sensitive to the removal of the endothelium. Atropine treatment did not block the vascular effect of high concentrations of pilocarpine. Atropine, as expected, blocked the vascular effects of carbachol with KB = 3.2 nM. Pilocarpine produces vascular relaxation by its competition with spasmogens like phenylephrine, oxymetazoline, vasopressin or latanoprost. Arecoline also shares these properties with pilocarpine in the blood vessel. The molecular mechanism of the vascular effects as well as ocular clinical implications of cholinomimetic drugs is discussed.

In vitro muscarinic activity of spiromuscarones and related analogs

The cholinergic hypothesis of Alzheimer’s disease suggests that cholinergic agonists may have therapeutic potential for treating the attendant memory deficits of the disease. As part of a program aimed at preparing metabolically stable, nonquaternary analogs of muscarone, 1-oxa- 2,8-dimethyl-8-azaspiro[4.5]decan-3-one, 2a, and related analogs have been synthesized and their in vitro muscarinic activity evaluated. The synthetic strategy in the formation of the 1-spiro[4.5]decan-3-one ring system of 2a involved cyclization of the diol 4 in the presence of Nafion-Hg. The spiromuscarone 2a was found to displace [3H]Oxo-M binding with a K(i) value of 7 nM. Affinities of the oxime and hydrazone analogs of 2a were lower than 2a. The compounds in these series were partial muscarinic agonists as demonstrated by stimulation of phosphatidyl inositol hydrolysis assay, with 2a showing the highest intrinsic activity (60% as compared with carbachol). The results from this study indicate that an exo double bond at the C-3 position is essential for the receptor binding.

Intriguing case of Pseudo-isomorphism between chiral and racemic crystals of rac- and (S)/(R)2-(1,8-Naphthalimido)-2-quinuclidin-3-yl, and their reactivity toward I2 and IBr

Condensation reactions between 1,8-naphthalic anhydride and racemic 3-aminoquinuclidine or chiral (S) or (R)-(-)-3-aminoquinuclidine allowed preparation of three novel racemic and enantiopure aza-donor ligands, namely NMiABCO (1), (S)NMiABCO (2a), and (R)NMiABCO (2b). Racemic NMiABCO (1) crystallizes in the monoclinic space group P21/c, Z? = 1, while enantiopure (S)NMiABCO (2a) and (R)NMiABCO (2b) crystallize in the chiral monoclinic space group P21, Z? = 2, and show significant pseudocentrosymmetry, being pseudo-isomorphous with racemic NMiABCO (1). Reactivity of both racemic and enantiopure NMiABCO toward iodine and interhalogen IBr was also investigated as a way to remove the pseudoisomorphism, yielding the three new molecular adducts [NMiABCO¡¤I2] (3), [(S)NMiABCO¡¤I2]¡¤xCHCl3 (4), [(S)NMiABCO¡¤IBr]¡¤xCHCl3 (5) and the molecular salt [HNMiABCO][IBr2] (6). Synthesis of complexes 3 and 4 was also carried out in the solid state via kneading and vapor digestion techniques. All compounds were fully characterized via single crystal and powder X-ray diffraction and Raman spectroscopy.

Muscarinic contraction in isolated guinea-pig trachea and antagonism by noradrenaline

In contrast to other muscarinic agonists, WAL 2014 FU does not induce bronchospasm in laboratory animals. The present investigation was intended to test the hypothesis that this is due to a particular susceptibility of the drug’s effect to antagonism by catecholamines, as a result of partial M3- agonism. The tonic activity of the muscarinic agonists, aceclidine, arecoline, carbachol, McN-A-343, RS 86, thiopilocarpine and WAL 2014 FU, was tested in groups of isolated tracheal muscle of the guinea-pig. Susceptibility to functional antagonism by beta-adrenoceptor stimulation was measured by the displacement of the concentration-force curves by 3 muM noradrenaline. Evaluation of the concentration-force relationship revealed differences in potency and intrinsic activity (carbachol=100%) ranging from 114% for arecoline to 36% for thiopilocarpine (WAL 2014 FU=63%). The catecholamine increased the concentration of agonist which induced 5% of the maximum effect achievable (EC05) values fivefold (carbachol) to more than 4,680 fold (thiopilocarpine) (WAL 2014 FU: 2,860 fold). Regression analysis between the intrinsic activity of the seven compounds and the antagonistic effect of noradrenaline revealed a significant correlation (Spearman correlation coefficient (r(s)) =-0.79; p=0,036). Inhibition of the effects of endogenous catecholamines by beta-adrenolysis with 50 muM toliprolol increased the maximal contraction induced by 1 mM WAL 2014 FU, but did not affect maximal contraction induced by 30 muM arecoline. Pretreatment with 0.3-1.0 mM dibutyrylcyclic adenosine monophosphate (DBcAMP) shifted the concentration- response curves of arecoline, WAL 2014 FU and thiopilocarpine in a similar manner to noradrenaline. The results exclude an important contribution of adenylate cyclase-coupled M2-receptors to the susceptibility of tracheal contraction by muscarinic agonists to functional antagonism by noradrenaline, but emphasize the importance of intrinsic activity at the M3-receptors. The pronounced susceptibility of WAL 2014 FU-induced contraction to functional antagonism by beta-adrenoceptor activation provides an explanation for the failure of the drug to induce bronchospasm in vivo.
